The player was training alongside World Cup internationals Messi, Piqué, Alba and Busquets at the Ciutat Esportiva
Mateu Jaume Morey 'Mate', who is player for the Barça B side, has suffered a torn meniscus in his left knee during this Wednesday's training session.
The medical tests have confirmed the seriousness of the injury and he'll be forced to go under the knife on an as yet unknown date.
The full back was training at the Ciutat Esportiva Joan Gamper with Barcelona's World Cup stars such as Lionel Messi, Gerard Piqué, Jordi Alba and Sergio Busquets.
Although 'Mate' is yet to make his debut with the B side in an official match, he's one of the players that Garcia Pimienta had planned on using this season.
